Body reserves mediate trade-offs between life-history traits: new insights from small pelagic fish reproduction [PDF]
Limited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. In particular, the cost of reproduction is well known to negatively affect energy investment in growth and ...

ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

The Northern Anchovy reduction fishery for the 1978-79 through 1981-82 seasons [PDF]
Nearly 49,000 metric tons (MT) of anchovies were taken during the 1978-79 season, followed by 32,390 MT in 1979-80, 60,678 MT in 1980-81 and 45,150 MT in 1981-82. A total of 14,076 fish was sampled during the four seasons for age, length and sex.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Fine-scale dietary changes between the breeding and non-breeding diet of a resident seabird [PDF]
Unlike migratory seabirds with wide foraging ranges, resident seabirds forage in a relatively small range year-round and are thus particularly vulnerable to local shifts in prey availability.

Mitigating slipping-related mortality from purse seine fisheries for small pelagic fish: case studies from European Atlantic waters [PDF]
The release of unwanted catches (UWC) from purse seines, while the catch is still in the water, is known as “slipping”. Once thought to be a benign process, compared to discarding UWC overboard from the fishing vessel, it is now recognised that “slipping”

ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.
